Novak Djokovic likely to miss US Open due to lack of vaccination – John Isner slams entry ban: ‘complete insanity’

Eisner also added the hashtag #science to his tweet, which apparently the 37-year-old wanted to hint at the fact that from a scientific point of view there are no grounds for not entering.

The American responded to a question from a Twitter user who wanted to know if there were active professionals who wanted Djokovic to participate. American colleague Tennys Sandgren agrees with Eisner.

Djokovic had already missed the Australian Open earlier in the year for the same reason. The Masters tournaments in Cincinnati and Montreal are also taking place in the run-up to the last Grand Slam tournament of the year without the Serbs.

John McEnroe urges Djokovic to start the race

John McEnroe also jumped alongside the 21-time Grand Slam winner. Even during Wimbledon, the tennis legend demanded: “I think politics has become very involved here. The same thing happened in Australia at the beginning of the year. Let Novak Djokovic enter the United States and play the US Open.”
